32 Henderson, Thomas C.Target-directed navigation using wireless sensor networks and implicit surface interpolationAbstract-This paper extends the novel research for event localization and target-directed navigation using a deployed wireless sensor network (WSN) [4]. The goal is to have an autonomous mobile robot (AMR) navigate to a target-location by: (i) producing an artificial magnitude distribution within th...2012-01-01
33 Riloff, Ellen M.Empirical study of automated dictionary construction for information extraction in three domainsA primary goal of natural language processing researchers is to develop a knowledge-based natural language processing (NLP) system that is portable across domains. However, most knowledge-based NLP systems rely on a domain-specific dictionary of concepts, which represents a substantial knowledge-en...Information extraction; AutoSlog; Across domains1996
34 Furse, Cynthia M.Capacitance and inductance sensor circuits for detecting the lengths of open- and short-circuited wiresThe length of an open- or short-circuited wire is linearly proportional to the capacitance or inductance of the wire, respectively. Several types of simple and inexpensive circuits are introduced to measure these values. Open-circuited (capacitance) measurements are very effective. Short-circuited ...Aging aircraft wire; Capacitance sensors; Fault detection; Inductance sensors2009-08
